fl '0 all 107mm it may concern Be it known that I, AMsrrnL GUEF'r-GRIN- mans, a citizen of Russia, and a resident of New York, in the county of New York and State of New York, havoinvented certain new and useful Improvements in'Bucco- Lingual Dental Attachments, of which the following is a full, clear, and exact description. r r i This inYention appertains to dental attachments generally,,and more particularly to a bucco-lingual attachment for use as a bridging for theinstallationof artificial teeth in the mouth of a patient.

Theprincipal object of the invention is to provide for an attachment of the character mentioned, and one of an extremely simple, inexpensive and efiicient construction'and arrangement, such. as will, when properly installed, act torigidly retain an artificial tooth, or teeth, in -position within the moutl ofa patient, but which will also allow for. .t-he removal of the tooth or teeth, when desired or necessary.

Another object. of :the invention is to provide fora bridgework of the class set forth, and. one-embodying a novelform of resilient attaching memberfor effecting the proper installation of a tooth, or teeth, in position within the mouth of the patient,

and which, whileacting to secure the tooth Figure 1 is a SlClB' elevationof a denture embodying the invention,

Figure 2 is an enlarged fragmentary sec tional elevation of the same, I V Figure 31s a plan v1ew,.partly 1n section, of an artificial tooth as it appears in bridged position between adjacent natural. J L teeth.

ferred embodiment of the resilient anchor V or mortise member of the attaching device,

Figure 5 is a plan view of the blank from which the resilient anchor or member 13 formed, and,

Figure l is a ers ect-ive view of the re- Figure 6; is a perspective View of the keeper or socket member to be detachably engaged by t-he'resilient anchor or mortise.

Referring to the drawing, the bridging attachment or device, as shown therein, comprises generally akeeper or socket member 10 to be suitably embedded in a filling or the like of a natural tooth of a denture A of a patients mouth, and an anchor or mortise -11 to be attached at one side of an artificial tooth and detachably engaged with the keeper or socket member 10, when the 1 parts are properly installed in position, two of the attachments or devices being employed in each instance of the bridging of an artificial tooth between adjacent natural teeth, substantially as shown in Figures 1 to 3, inclusive. I

The keeper or socket member 10 is preferably of a tubular form, rectangular in cross-section, and open at its outer or upper r I end, with a slotted opening 12 extending longitudinally of one 'of its flat side, faces.

and inwardly from its open endto a point immediately adjacent its lower closed end.

The anchor or mortise member 11 is formed to provide a central flange or tenon portion 13and fiange port-ions l and 14 disposed in right angular relation at the opposite sides of one of the'longer edge of the flange or tenon 13, with resilient tongue members 15 and15 arranged to overlie the flange portions 14 and 14 to either side of the said flange or tenon 13.

In its preferred embodiment, the anchor orv mortise member 11 is made from asingle piece or blank of sheet material, rectangu-- lar in plan as shown in Figure 5, which is cut-away mwardly of one of its ends, as at 16, to provide the spaced resilient tongue portions or'members 15 and 15. The portions ormembers 15 and 15 are to be bent on the lines of fold aa, on the transverse center of the blank, to positions overlying the corresponding portions or flanges l t and 14 of the other half portion of the blank, while the tenon 13 is to be formed by first bending the uncut portion of the blank on the line of fold b, on the longitudinal center thereof, and then, on the lines of fold n+0 to dispose the flange portions 14 and 14 outwardly therefrom in the desired right angular relation thereto. The resilient tongue portions or members 15 and 15 are normally inclined with respect to the flanges let and ,lt', so asto be compressed toward the opposed t'i cea ot the latter when the anchor or mortise ll is inserted downwardly of? the keeper or socket in, and whereln' the former is lrictionally retained against: :u-cidental displacement lrom en nigcment with the latter.

la the installation of an artificial tooth within the mouth of a patient. and between adjacent natural teeth B and ot the denture A. as shown in Figures 1 to 3. the adjacent sides of these natural teeth will. be drilled or otherwise opened up to receive in aeh a suitable filling" or inlay l) in which is to be embedded a socket member ll) with the slotted opening 12 thereof? exposed through the filling or inla v material. the slotted opening 12 oil the socket it) of the natural tooth .lPl being: arranged directly opposite to the slotted ol'ieningr oi the socket ol the natural tooth (i and in alignment therewith. The artificial tooth. or arti icial tooth denture 'lT'is now selected or prei'iared. and is suitably opened up at its opposite sides to receive the teuon portions 153 at? a pair of the anchorrs or mortises fl and. with the latter rigidly secured in position. the flange portions ll and l-l thereof will be insert ed downwardly of the respective keeper or socket lllOllllX-l'S 10. During the insertion of theflange portions ll and ll into the keepers or sockets lo. the resilient tongues 15 and l5 carried thereby will be placed under compression and will trictionally engage the opposed inner wall portions of the out-er flat faces of the keepers or rockets ltf to either side of? the slotted openings 12, and thereby act to retain the anchors or mortises ll so curelv in position against accidental dis placement.

It: will be obvious that the bridgeavork thus provided for will be exceedingly simple and inexpensive to manufacture, and, at; the same time, extremely ellicient and durable in be understood that the parts of the attaclr ment or device are. to be made from a noncorrosive flexible and resilient materiahsuch as are gei'ierally employed in the practice ot dentistry, and that the resiliency ot the tongue portions 15 and 15, of the anchor or mortise member ll, will beanaintained to provide for the proper frictional engagement of the latter with the keeper or socket member ltl by keeping the tongues in properly epaced relation to the flange portions fl and ll of the auchoror mortise 'f'l.

From the foregoing, it; will be readily apparent: that. while a preferred embodiment of the attachment or device has been described and illustrated herein in specific terms and details of cimstuction and arrangrement; various changes in and 1noditications at the same may be res-iorted to with out departing from the spirit of the invention. or the scope of the claim appended hereto.

llavingr thus inlli described the inrention. what is claimed, isz- As an article of nianu'fact'ure, a dental anchor comprising a blank of sheet mate rial of rectangular 'l'orn'iation and havinga cutaway portion at one edge thereof to pro vide spaced resilient tongue members at one side of the transveree center ot the blank, the opposite portion of the blank being; bent upon itself on the longitudinal center thereof to providea denture engaging tenon, the latter portion of the blank being further bent on lines parallel to and equidistantly spaced from the line of told of the said tenon to provide opposite angularly clisposed flanges, said resilient tongue n'iembers being bent lnickwardly upon said flanges and disposed in. spaced inclined relation with respect: thereto.
